Hi,
I just wonder if it’s possible/makes sense to dry Desiccant for AMS（6 pack） | Bambu Lab EU in a blast drying oven like PrintDry e.g.?
Contrarily to silica gel dessicant which can be reused after reheating, bambu dessicant is calcium chloride which when saturated cannot be reactivated and need to be replaced.

It is possible, but it doesn’t make sense to me.
If you have a blast drying oven that operates up to about 200ºC or higher, you can dry the calcium chloride; I wouldn’t recommend such a procedure because it demands more energy, work and risks.
I was surprised that PrintDry had a blast drying oven. Can you share more info? I couldn’t find it on their website.
As a reusable, desiccant material for desktop 3d printers, silica seems a wise choice.

I stand corrected then. I made some search following your answer and while it seems it can be regenerated (in its granular form apparently so not necessarily the bambu lab product), it needs 250°C.

I have been using a color changing rechargeable silica drying packets for three years now, well before my X1/AMS. The color change is great because it lets you know when you actually need to change them. I went from changing my storage bags monthly, to almost quarterly, and the recharge is like 7 minutes in the microwave (several do generally need a second zap to get them back to fully blue). They fit nicely between the loaders in the AMS so you can see when those need to be changed too, which is a lot more frequently. I have had to buy additional bags as my collection of spools in storage grew, but I have yet to have to throw out a single one because it didn’t recharge.
Search Amazon for " Dry & Dry 20 Gram" it will be the first entry after the sponsored links

You are aware this stuff contains Methyl Violet which is what gives it it’s orange colour, the following applies - although I couldn’t imagine anyone eating it.
AI Overview
Methyl violet (CI 42535) can be dangerous if it comes into contact with the skin or eyes, or if it’s inhaled or ingested:
Skin and eyes*: Contact with the skin or eyes can cause burns.
Inhalation*: Accidental inhalation can cause serious respiratory difficulties.
Ingestion*: Ingestion can cause internal damage.
Central nervous system*: Accidental contact can alter the central nervous system.
Unconsciousness*: In extreme cases, accidental contact can lead to unconsciousness.
Immediate medical assistance*: If ingestion or inhalation occurs, immediate medical assistance is required.
Heating it it one of the things that can cause it to become dangerous.
Ok, and? I don’t plan to eat it, or for that matter even touch it. It is contained in a nice little packet that you don’t need to open to use. I use two packets in each vacuum bag. The entire packet goes in the microwave with a bunch of others on a paper towel for 7 min at 40% power. No need to eat or touch it.
